Google Home Automation, Ezviz, sleep mode, geofencing

I'd like to switch on/off my Ezviz camera via google home. Also, I'd like to set and away/home automation that allows to remove/set sleep mode based on geofenncing for all people in the home. Is that at all possible? Tried but couldn't do it.

Also, I need more cameras and was thinking to get other Ezvizs so all are of the same brand BUT I am a bit unsure now that I can see that I cannot control (eg switch on/off, put to sleep) my Ezviz camera via Google Home and that I cannot find a decent way to allow home/away modes for multiple users using geofencing.

Thanks for your advice!
